The blktrace is a tool and I was wondering if there's something in / proc itself that I can use to get some info regarding the disk i/o per process. Yes, there is. echo 1 /proc/sys/vm/block_dump causes the kernel to log all I/O, so it all appears in your syslog. It's probably not something you want to leave switched on. :-) Tim -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

You don't say anything about operating system, but in Linux = 2.6.19 you can use blktrace, which gives you this information and much more. /* Steinar */ -- Homepage: http://www.sesse.net/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Re: status of disk i/o per process
Thanks for the reply Steinar. The blktrace is a tool and I was wondering if there's something in /proc itself that I can use to get some info regarding the disk i/o per process. Thanks again.
